I highlighted PARAMS removal because its something we'll allow as
"obvious" checkins.  But there's a lot more we can do for ISO C90
conversion.

E.g. as you suggested above, you can convert to the new function
definitions and use bool parameters.  But you can also convert
VPARAMS, DEFUN, PTR, VA_OPEN (really VA_*).  Also stuff from symcat.h,
namely CONCAT* and STRINGX.  You can also rely on using string
concatenation and other ISO C90 features if the current code was
uglified for traditional C compatibility.

All of these need to go through the standard review and approval
process and adhere to our coding style conventions but are definitely
part of the conversion.

I probably left something out, but use ISO C90 as your guide.
